UNITED STATES HOWARD I]. BURNS, OF DALLAS, TEXAS.

COMBUSTION CHAMBER FOR INGINERATORS.

Application filed August 24, 1925. Serial No. 52,916.

To all whom it may concern:

Be it known that I, HOWARD E. BURNS, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Combustion Cham bers for Incinerators, of which the following is a specification.

This invention relates to combustion chambers for incinerators.

In the construction of incinerators, it is usual to provide an incinerator chamber having grates on which the refuse is burned and to convey the products of combustion to a combustion chamber wherein the burning of the gases is completed to eliminate odors in the waste gases passing to the stack.

An object of the present invention is to remove foreign matter from the waste gases and thus eliminate smoke.

More specifically, I provide a combustion chamber having an inlet opening at one end communicating with the incinerator cham her and an outlet opening at the opposite end connnunieating with the stack and place a baflie plate transversely ofthe combustion chamber in front of the outlet opening which causes the gases to travel upwardly, thus producing eddy currents causing deposition 3 of any foreign matter in the gases.

In the accompanying drawings, I have shown one embodiment of the invention. this showing:

Figure 1 is a horizontal sectional view of a combustion chamber having the baffle plate arranged therein,

Figure 2 is a vertical sectional view on line 22 of Figure 1, and,

Figure 3 is a transverse vertical sectional view on line 3-3 of Figure 1.

Referring to the drawings, the reference numeral 1 designates generally the combustion chamber having side walls 2, a rear wall 3, and a front wall 4:. The walls of the combustion chamber are constructed of any suitable material and it may be provided with a top 5 having a curved wall 6 an ranged therebeneath to provide an air space 7. Adjacent the front of one of the side walls, I provide an opening 8 adapted to communicate with a flue 9 extending from the incinerator chamber (not shown). Adjacent the rear of the opposite wall, I provide an opening 10 communicating with a flue 11 extending to the stack (not shown). As shown, the opening 10 ext nds from the bottom of the combustion chamber to a point spaced from the top.

Forwardly of the out-let opening, -I provide a baflle wall 12 extending upwardly substantially the same distance as the outlet opening and extending from one side of the wall to the other.

The path of the gases through the combustion chamber is indicated by arrows in the drawings. The gases enter through the flue 9 and opening 8 to the front of the combustion chamber and travel rearwardly through the outlet opening 10 to the flue 11. During the period of time that the gases are in the combustion chamber, combustion is completed so that the gases delivered to the stack are substantially free of odor.

As shown in Figure 2 of the drawings, the

gases reachingthe bafiie wall 12 travel upwardly and thence downwardly to enter the flue 11 and in so doing, any foreign matter is deposited in the bottom of the combustion chamber, thus eliminating smoke from the stack or outlet.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. In a device of the character described, a supplementary combustion chamber having side walls and front and rear walls, said combustion chamber being provided with an inlet opening arranged in one of said side walls adjacent the front thereof and adapted to communicate with a furnace, said combustion chamber being further provided with an outlet opening arranged in the other side wall adjacent the rear and extending upwardly from the bottom of saidchamber to a point spaced from the top thereof, and a baffle wall arranged transversely of said combustion chamber intermediate said openings and extending upwardly from the bot tom of said combustion chamber to a point substantially in horizontal alinement with.

the top of said outlet opening.

2. In a device of the character described, a supplementary combustion chamber formed substantially rectangular in horizontal cross section and having side walls and front and rear wallsyone ofv said side Walls .being provided in the forward and lower portion thereof with an inlet opening adapted to communicate withthe interior of a furnace, the other of said side walls being provided adjacent the rear thereof with a relatively narrow vertically elongated outlet opening extending from the bottom of said combustion chamber to a point spaced from the top thereof and a transverse baffle 10 wall extending between the side walls of saidc-o-mbustion chamber intermediate said openings and in close proximity to said outlet opening, said bafiie wall extending upwardly from the bottom of said combustion chamber to a point substantially in horizontal alinement with the top of said outlet opening.

In testimony whereof, I affix my signature.

HOWARD E. BURNS.
